Not sure what you stated is dead wrong, but it for sure is wrong.
You should know better than that! pwm controllers need "big" cables for other reasons. High panel temperatures will lower PV voltage. Combine that with a sizable cable voltage drop and voltage at the controller can lower charge current.

His recommendation for HUGE cables with PWM controllers. Once you have cable that will carry the number of amps safely then there is no need to go larger.
